Letters Patent No. 83,676, dated November 3, 1868.

MPROVED MACHINE FOR CUTTING- MEAT i..

The chedule referred tn in :these Letters Patent and making partei the same.

Beit known that I, PETER VANDE SANDE, assignor to myself and STEPHEN COLEMAN, both of Rochester, in the county of Monroe, and State of New York, have invented a certain new and useful .Improvement in Machines for Cutting Meat and Other Materials; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specication, in whichl Figure 1 is a front elevation, 'and Figures 2 and 3, detail views, showing the arrange ment of the knives and clcarers.

Like letters of reference indicate corresponding parts in all the igures.

My invention consists essentially in the arrangement of the knives and clearers, and in the method of operating themeat-box.

In the drawings, A indicates the frame, having a stationary bed, B, on which rests' the meat-box (l, and

having also a vertically-acting gate, D, which receives motion, through pitmen E E, from double-crank 'shaft G. The gate is armed with vertical knives a, a, set at regular distances apart, and turning upon pivots b b,

by which means they may be adjusted to any angle,

as indicated in lred lines, fig. 2. 0n one side of the gate, the knives are jointed to a bar, c, to which is attached a rod, d, passing through an eye, j, with a pin, g, that lits invany one cfa series of adjusting-holes, h. By this means, the position of the knives is changed at one action.

Beneath the knives, and between them and the meatbox, is a viiexible rack, H, made up of clearers or crossbars, i i, pivoted at' opposite ends to straps k k, supported by the opposite sides or standards of the frame, as clearly shown in gfl. The opposite angular corners, Z l, adjust longitudinally by the same devices, j' g lt, as the parts above, so as to set the clearers at angles to correspond with the knives, indicated by the red lines, iig. 3.

4The meat or other material, being placed in box C, is fed along rst in one direction, and then the other, andthe knives, striking down through the spaces between the clearers to the bottom of the box, cut it up finely in the passage. When the knives pass up in the l upward stroke, the clearers or bars i i sweep them clean,

and thus prevent any cloggingor obstruction. When the meat has been suiciently cut in a straight line, the knives and clearers are set at any corresponding angle, and secured there, as indicated by red lines, gs. 2 and 3, which cross-cuts the contentsy of the box. By this means, the meat may be reduced to any desired degree of finenesswith but little labor. The flexibility or yieldingness of the rack H will allow the perfect action of the knives in both directions, for if any impediment comes between the gate and rack, the latter will yet yield sufficiently to allow the knives to complete their stroke, and therefore the machine will not be stopped.

This arrangement of the knives and elearers, capable oi' adjusting to different positions, forms an essential feaf ture in my invention, and the same I believe to be new In order to make the knives cut deeper or shallower in the box, I make the pitman-rods E E adjustable in length by screws m and sockets la.

On the crankshaft G is situated a series of collars, I I I, adi ustable to diiierent positions, and secured to the shaft by set-screws o. These collars are cut with screw-threads oi'dilierent degrees of coarseness, and of peculiar arrangement.

rihe threads are cut or divided longitudinally of the collar, on two opposite sides, 'as shown at 11, and the sections, q q, oi'said threads are made of diamond or doublewedging form, and the several points of the two sets break joints, or alternate in position, as clearly shown in iig. l; that is, the points of one set come opposite the openings of the other set. At this extremities of the screw-threads, the ends of the collars are formed `into two cams, lr lr, whose inclinations are parallel, as

clearly indicated in fig. 1.

The upper end of a thread-plate, K, lits loosely into the bottom of the meat-box, so as to have a free turning motionin its socket. The lower end has two forks, s s, which stride the collar, and work like anut between the screw-threads.

The action is asfollows: In leaving the screw-threads of one section, the thread-plate'- strikes into the screwthreads of the other section, and thus moves forward, carrying the meat-box till it reaches the end, when cam lr sets the threadeplate in the opposite direction, and it feeds back in the same'lnanner, thus making the action of the meat-box continuous and-reciprocating under the knives. Whenever it is desirable to feedfaster or slower, the screw-collar is moved out of place, and another with a dierent thread substituted. The loose connection oi' the box with the thread-plate allows the parts to be separated at once.

This arrangement oi the divided screw, whereby the thread-.plate can alternately reciprocate, I believe to be original with myself, and also the arrangement-of a series of the collars, with the threadsof different degrecs of coarseness, wherebyone may be replaced by another.

What I claim as my invention, and desire to secure by Letters Iatent, s-

1. The combination of the knives a and clearers it', having an a gular adjustment,and otherwise arranged as descri wed, and operating'in the manner and for the purpose specied.

2. Constructing the rack H in such a manner as to have a degree of liexibility, as herein described.

3- The arrangement 0f the divided SCI'CWt'h'CadS, q 6. The arrangement, as a \vhole,'oonsisting of knives 9: Pon the 0011911 l, in Such 3J manner as t0 alf/@mate Aa a, rack H, box O, thread-plate K, and soreW-collas in position when combined with the thread-plate K, in I, operating as described. v
